Nutraceutical potentials of algal ulvan for healthy aging
International Journal of Biological Macromolecules, 2022Several theories for aging are constantly put forth to explain the underlying mechanisms. Oxidative stress, DNA dysfunction, inflammation, and mitochondrial dysfunction, along with the release of cytochrome c are some of these theories. Diseases such as type 2 diabetes mellitus, intestinal dysfunction, cardiovascular diseases, hepatic injury, and even ...

Creation of the Ulvan Lyase Enzyme Complex for the Production of Ulvan-Derived Oligosaccharides
Journal of Agricultural and Food ChemistryUlvan, a primary constituent of green algae biomass, has the potential to be used for various biomedical and biotechnology applications. Its biological activity is significantly influenced by its molecular weight. However, the high molecular weight of ulvan poses challenges due to its high viscosity and poor solubility, necessitating an efficient ...

A Conformational Study on the Algal Polysaccharide Ulvan
Macromolecules, 2002The conformational behavior of the algal polysaccharide ulvan in aqueous solution has been studied. This biopolymer, containing limited regular regions of aldobiuronic sequences made of β-d-glcpA(1→4)-α-l-rhap 3-sulfate and of α-l-idopA(1→4)-α-l-rhap 3-sulfate, can be considered as a low-cost source of rare sugars with a potential impact on several ...

Multifaceted applications of ulvan polysaccharides: Insights on biopharmaceutical avenues
International Journal of Biological Macromolecules, 2023Ulvans are water-soluble sulfated polysaccharides predominantly found in the cell wall of green algae. They hold unique characteristics that are attributed to their 3D conformation, functional groups along with the presence of saccharides and sulfate ions.

The polysaccharide ulvan, composed of sulphated rhamnose, glucoronic and iduronic acids was used to produce polymeric membranes by solvent casting. As ulvan is soluble in water, a cross-linking step was necessary to render the membrane insoluble in water and stable at physiological conditions.

Ultrastructure of ulvan: A polysaccharide from green seaweeds
Biopolymers, 2009AbstractUltrastructural analysis of the gel forming green seaweed sulfated polysaccharide ulvan revealed a spherical‐based morphology (10–18 nm diameter) more or less aggregated in aqueous solution. At pH 13 in TBAOH (tetrabutyl ammonium hydroxyde) or NaOH, ulvan formed an open gel‐like structure or a continuous film by fusion or coalescence of bead ...

Antioxidant activity of purified ulvan in hyperlipidemic mice
International Journal of Biological Macromolecules, 2018Several studies have reported that ulvan from the alga Ulva pertusa (Chlorophyta) exhibits substantial antioxidant and antihyperlipidemic activities; however, which group of heteropolysaccharides play roles in these activities remains unknown. In this study, three purified ulvan (PU1, PU2 and PU3) have been obtained by DEAE-Sepharose fast-flow column ...

Biofunctionalization of Ulvan Scaffolds for Bone Tissue Engineering
ACS Applied Materials & Interfaces, 2014Photo-cross-linked ulvan scaffolds were designed with the aim to induce and support enzyme mediated formation of apatite minerals, in the absence of osteogenic growth factors. Scaffold formation with a desired geometry was investigated using chemically modified ulvan bearing radically polymerizable groups.
